Ductile manhole covers are common on roads, and Fuzhou ductile iron manhole covers are also the manhole covers we have used for a long time. However, after recent years of development and technological change, our new nodular cast iron manhole covers developed by our consumer have restrained the defects of traditional manhole covers, brought great convenience, and greatly facilitated our use. Well, what are the superior properties of the new nodular cast iron manhole covers we have seen? Let us introduce them for you by Xinxinhong Building Materials.
The appearance is beautiful; the materials used in the new nodular cast iron anti-theft manhole cover are high-quality ductile iron pig iron, coke and special nodulizers from specially designated consumer factories. It is close and the surface of the concrete well ring can not be exposed. Under the premise of maintaining flatness, the manhole cover is integrated into the road and the road to become an integrated city and beautify the effect. The old gray cast iron manhole cover, because of its dark manhole cover and rough appearance, the concrete well ring must expose the asphalt surface layer, the color and the asphalt surface layer are not different, the flatness is difficult to control, and it is difficult to integrate with the road.
The value of repeated use is not high; the old gray cast iron manhole cover has high cast iron content, and it is of high value for re-use.It often becomes the object of frequent visits by thieves. A well cover is broken into pieces and sold to private buying stations. Ductile iron anti-theft manhole cover is synthesized from several materials, contains a lot of impurities, and the value of repeated processing and recycling is not high. This is a basic method to effectively prevent small theft.
The price is reasonable; the price is reasonable based on different specifications. The price of the new nodular cast iron anti-theft manhole cover is higher than the price of the old gray cast iron manhole cover.
